Recent results on rare K + decays from BNL E787
- Conference date: 23−29 May 1991
- Location: Tucson, Arizona (USA)
Experiment 787, now in progress at Brookhaven National Laboratory (BNL), is designed to measure the process K +→π+νν̄. A preliminary upper limit for this process was recently obtained Γ(K +→π+νν̄/Γ(K +→all)<5×10−9 (90% c.l.). A major upgrade of the experiment will take place in the coming year, involving a new beam line and replacement of several detector components in order to enable higher sensitivity for the measurement.
